IMPROVEMENT IN BURRINGCY'LI'NDERS IOIIR. WOOL, 8m'.

Be it known that I, CHARLES G. SARGENT, of West ford, in the State of Massachusetts, have invented a new and useful Improvement in Cylinders for Bur-ring Wool, Ginnin g Cotton, and cleaning fibrous substances,

of which the following, with the drawings, is a full deportions of which become so thoroughly incorporated with the wool as to be found in the finlshedvcloth after passing through all the 'manipulations of manufacturing.

When the foreign matter is very tine and minute, each tooth must be made so as to grasp only one or two bres at a time, causing -an even distribution of bre over its surface, and insuring the separation of theV foreign matter by the action of the guard or retaining- It has been found very diihcult in manufacturing burring-cylinders to cut the teeth sufficiently small andfne to take the requisite quantity of nine, and no tool has been made to cut the teeth small enough; and heretofore, when cylinders have been made, they have been made alike with the same quality or capacity of tooth for all purposes, or else it has been found necessary to make diii'erent cylinders for diierent kinds of work.

When the cylinders have been once made, the capacity of their teeth is fixed, and while they have been large enough for coarse fibre, they have never been small enough `for the finest.

There have been no means used to varythe capaci-ty of the tooth after the cylinder was once made.

My invent-ion is intended to obviate these difhculties by the introduction of a soft binding or packing-wire between the rows of teeth.

By this means, the teeth of cylinders can be punched sufficiently large for the coarsest stock, and the capacity of the teeth can be regulated for any grade to the finest. v

The wire heingpacked in under a pressure, tends to crowd into the notch of the tooth, while it diminishes its depth each side and strengthens and supports it, as gell as regulates its quality or capacity for receiving bre.

In this way, I make a new clothing for the cylinder,

. and a new surface, of hard teeth 'and soft wire.

To make a perfect cleaning-surface for the mestizo and Cape wools, this packing and binding wire must fill np between the rows of teeth to nearly an even surface, `barely lem-'ing a notch ory tooth sufficient to catch a bre or two of stock.

I believe this has never before been done in any cylinder.`

Besides this, with this-arrangement, as the tooth Wears` away, the binding-wire may be turned down on its top side and leave atooth as 'good as at rst, and so on till the tooth is worn out.V

In the drawings- Figure 1 is longitudinal view, showing toothed wire and softpacking-wire between.

Figure 5 is a cross-section, with a delta-shaped toothed wire, an inverted (V) truncated delta-shaped packing-wire.

Figure 6 is a longitudinal section of part of fig. 5.

e e, figs. 2, 3, 4, is'a ribbed toothed wire, the teet being' cut on the dat part above the rib.

fj, figs. 2 and 4, is a spiral groove, out in the sur# face ofthe cylinder, in which the rib of the toothed wire is placed and staked down. I

g g, figs. 2, 3, 4, is a packing-wire, of soft eoppergor othersoft metal, which is packed or crowded in between therows of toothed wire.

e e, figs. 5, 6, 7, is an angular toothed wire, and

g g, gs. 5, 6, 7, is an angular packing-wire.

InV covering or clothing the cylinder, IputA it in a common screw-nuttin g lathe, and whenI use the ribbed wire, I cut athread or groove spirally on its entire length, and then wind the Wireinto the lgroove and stake it down. Then'the soft packing-wire is wound round between the .rows of toothed wire, a staking-roller being placed on it, so as tocornpress it very closelyY .on the surface of the cylinder and between the toothed wire, and if the pressure is sufficient, it will crowd it also in between the teeth of the same row, more or less.

l The wire may be -flattened, or, in some cases, used round.

In som e' instances, l fasten one end ofthe tooth ed wire to the surface of the cylinder, and then set the lathe in motion and wind it round the whole length and fasten it, and then wind the soft Wire between, applying the staking-roller, so as to press it firmly between the teeth, or both wires maybe wound at once.

I thus produce a new surfaceof hard teeth and soft wire.

i I am` also enabled to 4vary and adjust the capacity of theteeth after they are made.

I am also enabled, by turning down the soft wir. to

Figure 4 is enlarged longitudinal section of part of use the same cylinder for the same work, till the teeth are Worn ont.,

I once obtained a patent for my wire-toothed clothed cylinder. I now desire a patent for my. soft-Wire packing clothed cylinder.

Teeth were old then; packing is 01d now; but wire teeth were new then, and. wire packing` is new now, as applied and -used by me.

What I claim as my invention, is-

A cylinder, for opening and cleaning fibrous materials, 85e., having a surface composed of alternate rows of hard teeth and soft packing-wire, the teeth being constructed substantially as shown, and the surface of the soft wire lying above the bases of the teeth and packing closely against the sides of the teeth, all

4substantially as and for the purposes described.

In testimony whereof, I have hereunto subscribed my name.
